How to Fix / Troubleshooting
Safety first: Unplug the dishwasher and allow it to cool before working underneath.
- Check for obstructions: Remove filters and inspect the sump for foreign objects that could jam the pump.
- Access pump: Remove the bottom panel and inspect the circulation pump for signs of overheating or burning.
- Test motor: Measure winding resistance and check for continuity to ground. Replace the pump if readings are abnormal.
- Inspect wiring: Check the harness from the pump to the control board for damage.
- Control board: If the pump tests good but E20 persists, the main PCB may have a motor driver issue and should be serviced by a professional.
